[1/1 Formula]
    Work: Calculate the value of equation arctan(20/7.5)-arctan(20/7.5)-arctan(20/100) .
    Question type: Mathematical calculation
    Solution:
          arctan(20/7.5)-arctan(20/7.5)-arctan(20/100)
        =arctan2.666667-arctan(20/7.5)-arctan(20/100)
        =arctan2.666667-arctan2.666667-arctan(20/100)
        =arctan2.666667-arctan2.666667-arctan0.2
        =1.212026-arctan2.666667-arctan0.2
        =1.212026-1.212026-arctan0.2
        =1.212026-1.212026-0.197396
        =0-0.197396
        =-0.197396

    Answer:arctan(20/7.5)-arctan(20/7.5)-arctan(20/100)=-0.197396
